When a cell becomes senescent it ceases replication, expands in size, and secretes a mix of pro-growth, pro-inflammatory molecules known as the senescence-associated secretory phenotype (SASP). Cells become senescent throughout life, mostly upon reaching the Hayflick limit on replication. Forms of damage, particularly DNA damage that might lead to cancer, the signaling of other senescent cells, and a toxic environment can …
